The taper of each preparation on the abutment teeth must be the same. This is known as parallelism among the abutments and allows the bridge to fit onto the abutment teeth. Adhesive bridges require minimal preparation. Master impressions: An accurate impression should be made of the prepared teeth, along with an impression of the opposing arch ...
A removable partial denture (RPD) is a denture for a partially edentulous patient who desires to have replacement teeth for functional or aesthetic reasons and who cannot have a bridge (a fixed partial denture) for any reason, such as a lack of required teeth to serve as support for a bridge (i.e. distal abutments) or financial limitations.
They consist of two parts referred as the 'male' part that is fixed to a crown inside the patient's mouth and a 'female' part which holds the partial denture. The patient can insert and remove the partial dentures and the aim of the precision attachment is to give the patient maximum comfort and ease while wearing, inserting or removing.
Dentures can help people via: Mastication: chewing ability is improved by the replacement of edentulous (lacking teeth) areas with denture teeth.; Aesthetics: the presence of teeth gives a natural appearance to the face, and wearing a denture to replace missing teeth provides support for the lips and cheeks and corrects the collapsed appearance that results from the loss of teeth.

The teeth used to support the bridge are called abutments. A bridge may also refer to a single-piece multiple-unit fixed partial denture (numerous single-unit crowns either cast or fused together). The part of the bridge which replaces a missing tooth and attaches to the abutments is known as a "pontic".
One major advantage of the resin-retained bridge over a conventional bridge is the failure mode is likely to be debonding of the retainer. In conventional bridges, the failure mode is likely to be complete fracture of the abutment tooth with difficult-to-manage sequelae, possibly requiring root canal treatment. With a resin-retained bridge the ...
